Have this problem. Camera,a PowerShot A400turns on ,lens extends,lcd lights up,then camera goes into time/date menu and that's as far asit goes. Can't use back rocker switch to set time/date. Can't change menu screen with any other buttons on back either. Camera acts as if back panel isn't connected. Both batteries and cell battery are new. Any suggestions? thanks

Fixed one problem,the ribbon cable to back panel wasn't seated. Reseated cable.everything on back panel now works. New/old? problem;lcd is blank when in record/movie mode,pics/movies,that are taken,come out black,everything else,the zoom,the flash,self timer,etc. works fine. Playback mode is fine,as long as you view pics on memory card from another camera. Has this Powershot A400 been recalled for bad ccd,like the other Powershots? Anyone have cross-reference sheet on ccd replacements? thanks
